[Industrial applications]

 The present invention relates to the decoration of eyeglass frames.

[0002]

[Prior Art]

 The spectacle frame is a device for holding the lens, and it is desirable that the spectacle frame does not cause fatigue even if worn for a long time. Therefore, in recent years, metal frames such as titanium, which are light and have a high spring property, are often used. However, the spectacle frame is not only required to have such functionality that it is light and easy to wear, and that it does not cause tiredness, but design and decoration are important in terms of wearing it on the face. The metal frame such as titanium described above uses a thin wire rod, so the frame has a certain degree of designability even before special secondary processing for decoration. However, painting or plating, or Often printed.

By the way, there is a method using a laser beam as one of the decoration processing of the spectacle frame. Japanese Patent Application Laid-Open No. 56-165584 "Glass Frame Ornament Processing Method" is a conventional example, but the processing method is "a core is made of a metal having a glossy surface, and this metal is made of a non-metal material. It is a frame that is covered by a jacket that projects a laser beam on the surface that exceeds the energy required to vaporize the jacket. ” Therefore, the surface coat on which the laser beam is projected partially evaporates and the glossy metal core is exposed to form a kind of pattern.

The “decorative member” according to Japanese Patent Laid-Open No. 54-56576 is also a technique of forming by irradiating a laser. That is, when the surface of the member is irradiated with a laser, it is melted to form an amorphous layer, and the color of the amorphous layer is different from that of other surface portions, so that a kind of pattern pattern can be formed. Further, when another metal powder is placed on the surface of the member and irradiated with a laser, the metal surface is melted and the metal powder is diffusion-welded, so that a pattern different in color from the other parts is formed.

As described above, the technique of utilizing the projection of the laser beam for decoration processing is already known, but in these conventional techniques, a concave groove is formed on the surface of a member such as a spectacle frame by projecting the laser beam. It is a pattern that is formed by discoloring or partially discoloring the surface. In other words, the processed area is limited to the surface of the member, and the pattern formed is only planar, so that dirt may be attached to the groove or discoloration may occur.

[Problems to be solved by the present invention]

 As described above, the laser beam can be used as one means for the decoration processing of the eyeglass frame, but the conventional laser beam decoration processing is planar due to the unevenness and discoloration of the surface, and the present invention is intended to solve the problem. The problem is the problem of the above-mentioned flat decoration. Therefore, the present invention provides a three-dimensional (depth) decorative body that is processed by using a laser beam, and aims at higher-grade eyeglasses.

[0007]

[Means for Solving the Problems]

 The spectacle frame ornament of the present invention projects a laser beam to change the color of a predetermined area to form a pattern, which is common to the prior art. However, the decorative body of the present invention is not limited to the outer surface of the spectacle frame, and a pattern is formed from the surface to a predetermined depth, and a pattern having a three-dimensional effect is formed by the bending phenomenon of light. Therefore, the spectacle frame has an opaque layer in the transparent layer or the semitransparent layer, and the above pattern is formed on the surface of the opaque layer. That is, the laser beam passes through the transparent layer and discolors the surface of the opaque layer to form a pattern, thereby forming the opaque layer at a predetermined depth.

Here, the material of the opaque layer is not particularly limited, using metal pieces, celluloid pieces, paper, ceramics, etc., and is formed by non-uniformly kneading the opaque resin in the transparent resin. You can also do it. In the present invention, the opaque layer is formed in the transparent layer at different depths, so that the pattern formed on the surface of the opaque layer gives a three-dimensional effect. The metal surface that is provided and becomes the opaque layer has the same depth, but such a case is also targeted. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

【Example】

 FIG. 2 shows a general molding frame. The molding frame is made of resin and is injection-molded. A lens is fixed to the front frame 1, and temples 2 and 2 are flexibly connected to both sides via hinges. By the way, when a transparent resin is used as a material for the molding frame and an opaque resin is mixed in the resin for molding, the opaque resin is mixed nonuniformly at the same time as molding, and a kind of opaque layer is formed. The opaque layer has different depths depending on the location. FIG. 1 is a model diagram in which an AA cross section of FIG. 2 is enlarged, and an opaque layer 4 is scattered everywhere in the transparent layer 3. When an opaque resin is mixed and molded, a continuous layer is formed without the opaque layer 4 being discontinuously scattered as shown in the figure, but this is simplified for convenience of explanation. The opaque layers 4, 4, ... As shown in the figure are formed when metal pieces or ceramic pieces that do not melt at the injection molding temperature are mixed.

Therefore, when the laser beam 6 is projected from the surface 5 of the crane 2 on which the opaque layers 4, 4, ... Are thus formed, the laser beam 6 passes through the transparent layer 3 and hits the opaque layer 4. The opaque layers 4, 4 ... Have different depths from the surface 5, but the surface 7 of the transparent layer 4 is discolored by the projection of the laser beam 6. The projection of the laser beam 6 is computer-controlled and moves along a predetermined path, and is generally formed as a kind of pattern or figure. However, since the depth of the opaque layer 4 that changes color with the movement of the laser beam 6 changes every moment, the formed pattern has a three-dimensional effect. As described above, such a three-dimensional pattern is brought about by changing the depth of the opaque layer 4, but even if the opaque layer 4 is formed to have a constant depth, the transparent layer 3 is The bending phenomenon of the passing light gives the pattern a three-dimensional effect.

Therefore, the transparent layer 3 is formed by applying resin to the outer surface of the metal frame, and the discolored pattern formed on the metal surface by the laser beam 6 projected from the surface of the transparent layer 3 is also the same. Has a three-dimensional effect. Of course, a metal piece may be embedded in a part of a molding frame made of resin instead of the metal frame, and the transparent layer 3 may be formed on the surface of the metal piece. By configuring the eyeglass frame ornament of the present invention as described above, the following effects can be obtained.

[Effect of the device]

 The decorative body of the present invention is a discolored pattern formed by projecting a laser beam, and the pattern is formed on the opaque layer located at a predetermined depth from the surface of the frame. Therefore, not only when the depth of the opaque layer varies depending on the region, but also when the depth is constant, the bending phenomenon of light passing through the transparent layer gives a three-dimensional effect to the pattern, resulting in a flare. It has a heavy decorative effect compared to the conventional laser beam pattern formed only on the surface of the frame. Moreover, since the pattern is not exposed on the surface, there is no fading and no discoloration due to the adhesion of dirt.
